Underwater Tunnel

At 112 metres long and holding a million gallons of water, the underwater tunnel at Deep Sea World is one of the longest underwater tunnels in the world.

When you are standing in the underwater tunnel, the curvature of the 6.5cm thick acrylic makes everything appear about 30% smaller than it actually is. So when you see our large sharks, just imagine how big they actually are!

The arched shape of the acrylic gives the tunnel the strength to hold back the enormous weight of millions of litres of water. In fact, the acrylic is the same material used by NASA in space shuttles and each panel of acrylic can withstand the weight of two African elephants!

The Sand Tiger shark is the largest shark to be displayed at Deep Sea World and can grow up to three and a half metres in length.

Sand Tiger sharks are also known as grey nurse or ragged tooth sharks and are normally found around Australia, Africa and America. Click the video on the left to see one of our sharks being fed!
